There’s a great article on the Langdon Wind Energy Center in North Dakota Living.  It details how rural North Dakotans worked together to bring a significant wind farm to the state. 

From the article:

The Langdon Wind Energy Center is capable of generating enough electricity to power nearly 40,000 homes, or 159 megawatts (MW). Initial operation of the 106 wind turbines began in December 2007, with Minnkota Power purchasing 99 MW. Otter Tail owns 27, or 40.5 MW, of the center’s turbines. FPL Energy owns the remainder of the turbines and operates the entire wind farm. All of the remaining output is sold to Minnkota and Otter Tail under long-term contracts. FPL Energy plans to build an additional 40.5 MW, or 27 turbines, this fall, bringing the total size of the project to 199.5 MW.

Apparently, the wind farm has had a powerful positive impact on the local economy, which is measured by an increase in tax revenues.
